Kate Major Arrest Report: What a Psycho!

That's the main takeaway from a police report filed after her arrest in Boca Raton, Fla., this weekend. If you missed it, Jon Gosselin's and Michael Lohan's ex-GF was jailed for battery after she was seen BEATING THE CRAP OUT OF A GUY AND HIS WIFE.

Police say Major allegedly had to be restrained on the ground by several people who saw her attacking and screaming at Rosario Tapia and Juan Jimenez.

The officer who wrote the report says, "I attempted to speak with [Kate Major], who was screaming and yelling obscenities at Tapia, calling her a 'fat f**k' and a 'b*tch'."

Jimenez told police he and Tapia pulled into the parking lot and noticed someone had parked in their assigned space, so they were waiting for another spot to open.
